To all whom it may concern:

Be it known that I, LAWRENCE V. DAVIS, a citizen of the United States, residing at South Bend, in the county of St.-Joseph'and State of Indiana, have invented certain new and useful Improvements in Roller Skates,

' of which the following isa specification.

Theinvention relates to roller skates, and has for itsobject -..to provide a devicefof this character, themain frame of which is formed from .asingle stamping, which may be severed transversely :for forming two sections and provided with means for receiving an adjusting bar whereby theframe maybe shortened or lengthened according ,to the size of the Vfoot'of the user, and at the same" time allowing the same diesto be'used for the-ivarious sizes of skate Zframes, therebyreducing'thejcost of manufacture to a min .1; Q a A further object is to provide the frame,

7 during the stamping operation with a longi tudinally disposed downwardly extending stiffening fchannelfor the reception of an adjustingbar, and the ends of saidchannel with enlarged depressions, the bottoms of which incline downwardly from the ends ,of the frame towards thecenter of -the frame, and downwardly struck flanges. carriedby the bottoms of thei 'depressions for the re ception of the roller trucks. a

A further object is to provide the opposite sides of the frame, adjacent its forward end with downwardly extending integral flanges. having-guides therein for the toe clamps, thereby obviating the use of rivets and special separable parts for "guiding the toe clamping members. o

A further ob'ect is to provide the frame adjacent its forward end with a downwardly struck lug'substantially' centrally thereof, which lug "is provided withasegmentally shaped recess engag ng an annular groove in the toe clamp ad ust1ng screw for pre-' venting axial movement ofthe screw duringv the clamping operation.

A further object is to provide a roller skate frame having a longitudinally disposed stiffening channel, toe clamp guiding flanges and doiiuiwardly'struck truck receiv-' ing flanges, all of which-parts-are formed from a single piece. of metal and in avsingle stamping'operation. I j With the above a' d-other'objects in view the invention-resides in the combination and arrangement of parts as hereinafter ,7 set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the' scope of what claimed without departing from the spirit of'the invention.

Referringgtothe drawingsthenumeral designates the Vm'ainbodyof the frame of the ,skate,v,which* body is provided with a downwardly struck longitudinally disposed channel 2, which stiffens theibody 131' and forms alongitudinally disposed rec'e'ss3,

which receives the ends of theadjusting bar 4 after the skate has. been formed, and the frame severed transversely at5fi-for formingfront and rear skate sections 6' and. The. ends of the channelQ'terminate in downi wardly struck enlarged recesses 58, the bottoms 9, of which incline downwardly from the outer end of the sections 6-and 7v towards the center of the skate, andinto' which r'e-x cesses the ends of the adjusting bar l extend. Bottoms 9 of the .recesses 8 are provided with downwardly extending parallelfianges 10, which are struck out :from the bottoms 9,

and which flanges are provided with aper-' tures' 11 for the reception of the pins 12, which pins extend through theflanges 13, of r the skate trucks '14 and rockably secure said trucks tothe skate frame; It will be seen the enlarged recesses 8 and flanges 10 may be formed in a single stamping operation and from a single piece of metal. The rear end of the skate section 7 is provided with a heel guard 15, whichheel guard is provided with strap receiving slots 16, and the heel guard is formed during the single stamping operation referred to. Trucks 14 are formed from a single piece of metal bent to form, and to provide cylindrical portions 17 which form bearings for the axles 18 of the skate, and on the ends of which axles rollers [19 are rotatably mounted, which rollers may be of any construction, however they are preferably provided with anti-frictional bearings: 20 as shown in'l igure 6.

Extending downwardly from the opposite sides of the skate sections 6 adjacent its forward end are longitudinally disposed flanges 21', which flanges are struck down- Wardly during the formation of the skate frame, and are provided with guide bearing recesses 22 in which the skate clamping members 23 are slidably mounted, therefore it will be seen it will not be necessary to userivetsand other separable parts for forming guides for the clamping members 22, and the guide recesses may be formed during the stamping operation if desired. 1 Clamping members 23-extend under the frame sections 6 and are provided with downwardly extendingflanges 24, through which are 29 of. the adjusting screw 26, consequently threaded the right and left handed portions 25 of the adjusting screw 26, therefore it will' be seen that when the adjusting screw 26 is rotated the toe cl'amping member, 23 will be moved towards or away from: each other according to the: direction of rotation of the adjusting screw. j To insure movement of the clamping members 23 relative to each other and tothe skate frame, the skate section. 6 is provided with a downwardly struck lug 2.7, the lower end of which is provided with segmentally shaped recess 28, and

which recess receives the reduced: portion axial movement of the adjusting screw-is prevented during its rotation 1n either directio-n. 'Interposed between the trucks 14 and the bottoms of the: recesses or depressions 8 are yieldable cushions 30, which cushions allow transverse rocking of the skate frame inrelation to the truck during a skating operation, but normal-1y maintain the axles 18 in a. parallel plane to the frame.

From the above it will be seen that a roller skate is: provided wherein the frame, the reskate be cheaply manufactured and sold,

It will! also be seen that the frame-can be skates, and may be extended to various lengths by means of the adjusting bar 4, through which bolts 31 extend and which bolts extend through the opposite sides of the channel members 2., By this adjusting means it is obvious a single setof dies may be used for manufacturing theskate frame, thereby obviating the use of a plurality of sets. of dies for varioussizes of skates.

Tlie'invention having been set forth what is claimed as new and useful is 1-- 1. A skate comprising forward and rear frame sections, downwardly struck alined reinforcing channels carried by said frame sections, truck attachingmeans in the bottom of said channels, and an adjusting bar disposed in said channels and connecting said frame sections. g

2'. A skate comprising forward and rear frame sections, downwardly struck alinedre inforcing channels carried bys-aid framesections, downwardly struck truck attaching nating in enlarged downwardly struck :por-' tions, the enlarged 'downwardlystruck p'org tions having their bottoms inclined downwardly and inwardly from the ends of the skate, said bottoms being provided with downwardly struck spaced flanges, skate trucks attached to said flanges, and an adj usting bar disposed vin thechannels and forming means for adjustably connecting the frame sections together;

4.. The combination with a skate comprising adjacent front and rear sections, alined channels in said sections, an adjusting bar in said alined channels and connecting said sections together, of downwardly struck spaced flanges in the outer ends of the chaninels, and trucks connected to said downwardly struck flanges. a s

5. The combination with a skate. compris ing front and rear sectionshaving alined downwardly struck channels, a connecting bar disposed in saidchannels, the ends of said channels being provided with down wardly and inwardly inclined bottoms, of downwardly and outwardly inclined struck out flanges carried by said bottoms ,anid skate trucks attachedto said flanges.

6. A skate frame comprising a body portion, a downwardly struck longitudinally disposed reinforcing channel carried by the body portion, the ends of said cl-ian' nel terminating in upwardly inclined porticns,

downwardly struck spaced truck receiving flanges carried by the inclined portions, and

1 means for attaching a truck to said flanges.

7. A skateframelcomprising a body portion, a downwardly struck longitudinally disposed reinforcing channel carried by the body porticn; the ends of said channel ter-.

minating 1n upwardly inclined porticns, downwardly directed spacedflanges' carried by said inclinedportions, andmeans for attaching a truck to said flanges.
